Benefits of technology

The present invention describes the discovery of a compound called salinomycin that has the ability to restore the function and morphology of aging-induced cells and prevent or treat various diseases caused by cellular aging. It can also be used as a skin whitening and life extension composition.

Problems solved by technology

Salinomycin is a monocarboxylic polyether antibiotic isolated from Streptomyces albus, and is used as a therapeutic agent for coccidiosis, a parasitic disease in chickens, but no specific efficacy against senescent cells has been reported yet.

Embodiment Construction

> Cell Culture

[0051]Human dermal fibroblast (HDF) and human umbilical vascular endothelial cells (HUVEC) were purchased from LONZA Inc. In (Walkersville, Md.), and human retinal pigmented epithelial cells (ARPE-19) and HK2 cells (human tubular epithelial cells) were purchased from ATCC (Manassas, Va.), respectively and used.

[0052]Human fibroblasts were cultured in DMEM (Dulbecco's Modified Eagle Medium) culture solution containing 10% fetal bovine serum (FBS), human umbilical vascular endothelial cells were cultured in EGM-2 culture solution, human retinal pigmented epithelial cells were cultured in DMEM:F12 culture solution containing 10% FBS, and HK-2 cells were cultured in RPMI1640 culture solution containing 10% FBS.

[0053]Cells (2×105) were dispensed into a 100 mm culture dish and subcultured in a 37° C., 5% CO2 incubator. When the cells grew to 80-90% in the culture dish, the cells were separated from the culture dish by treatment with a trypsin-EDTA solution, and the number of...

Abstract

The present invention relates to a composition for preventing or treating cellular senescence-associated diseases comprising salinomycin as an active ingredient, which acts differently depending on the type of senescent cells, and it was confirmed that salinomycin exhibits a senomorphics effect of restoring the function and morphology of fibroblasts and vascular endothelial cells in which senescence is induced and exhibits a senolytics effect of selectively killing aging-induced retinal pigmented epithelial cells, and exhibits a senomorphics effect of restoring the function and morphology of cells, and thus the salinomycin acts differently depending on the type of cells to effectively prevent or treat senile eye disease, tissue fibrosis disease, atherosclerosis, osteoarthritis, degenerative brain disease, chronic skin damage, obesity and diabetes caused by cellular aging and can be provided as a composition for life extension.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a U.S. National Stage Application of International Application No. PCT / KR2019 / 013373, filed on Oct. 11, 2019, which claims the benefit under 35 USC 119(a) and 365(b) of Korean Patent Application No. 10-2018-0161044, filed on Dec. 13, 2018, in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference for all purposes.TECHNICAL FIELD[0002]The present invention relates to a composition for preventing or treating cellular senescence-associated diseases comprising as an active ingredient salinomycin, which acts differently depending on the type of senescent cells.BACKGROUND ART[0003]Senescent cells accumulate in individual tissues and organs with aging, and accumulation of senescent cells not only induces changes in the function and structure of tissues and organs due to aging, but also plays an important role in the etiology of various senescence-associated diseases such ca...
